TITLE : Unit 10: Endocrine System SUGGESTED DURATION : 4 days

Unit Overview

Introduction

This unit bundles Student Expectations that address the structure and function of the endocrine system.

 

Prior to this Unit

  • Biology
    • B.4 – The student knows that cells are the basic structures of all living things with specialized parts that perform specific functions and that viruses are different from cells. The student is expected to:
      • B.4A – Compare and contrast prokaryotic and eukaryotic cells, including their complexity, and compare and contrast scientific explanations for cellular complexity.
      • B.4B – Investigate and explain cellular processes, including homeostasis and transport of molecules.
    • B.5 – The student knows how an organism grows and the importance of cell differentiation.
    • B.9 – The student knows the significance of various molecules involved in metabolic processes and energy conversions that occur in living organisms. The student is expected to:
      • B.9A – Compare the functions of different types of biomolecules, including carbohydrates, lipids, proteins, and nucleic acids.
    • B.10 – The student knows that biological systems are composed of multiple levels. The student is expected to:
      • B.10A – Describe the interactions that occur among systems that perform the functions of regulation, nutrient absorption, reproduction, and defense from injury or illness in animals.
      • B.10C – Analyze the levels of organization in biological systems and relate the levels to each other and to the whole system.
    • B.11 – The student knows that biological systems work to achieve and maintain balance.             

 

During this Unit

Students analyze the various methods in which hormones regulate metabolic activities. Students evaluate the use of feedback mechanisms in the relationship between the nervous and endocrine systems during the body’s response to stress.

 

Streamlining Note

In Biology TEKS B.4A, students now compare and contrast scientific explanations for cellular complexity in addition to previous expectations. Students no longer compare the structure of biomolecules in Biology TEKS B.9A but continue to compare the functions. The former Biology TEKS B.11A, describe the role of internal feedback mechanisms, was removed during the streamlining process implemented in 2018-2019. Students continue to understand the concept of process regulation in animals in the context of TEKS B.10A and homeostasis at the cellular level is addressed in TEKS B.4B.

                                                 

After this Unit

Students will use the information gained in this unit to understand how the communication and control functions of the endocrine system regulates the actions of other body systems.

 

Research

“By the end of the 12th grade, students should know that:

  • Communication between cells is required to coordinate their diverse activities. Cells may secrete molecules that spread locally to nearby cells or that are carried in the bloodstream to cells throughout the body. Nerve cells transmit electrochemical signals that carry information much more rapidly than is possible by diffusion or blood flow.
  • The human body is a complex system of cells, most of which are grouped into organ systems that have specialized functions. These systems can best be understood in terms of the essential functions they serve for the organism: deriving energy from food, protection against injury, internal coordination, and reproduction.
  • There are different traditions in science about what is investigated and how, but they all share a commitment to the use of logical arguments based on empirical evidence.
  • The dissemination of scientific information is crucial to its progress. Some scientists present their findings and theories in papers that are delivered at meetings or published in scientific journals. Those papers enable scientists to inform others about their work, to expose their ideas to criticism by other scientists, and, of course, to stay abreast of scientific developments around the world.
  • Scientists can bring information, insights, and analytical skills to bear on matters of public concern. Acting in their areas of expertise, scientists can help people understand the likely causes of events and estimate their possible effects.
  • Because science is a human activity, what is valued in society influences what is valued in science.
  • The human ability to influence the course of history comes from its capacity for generating knowledge and developing new technologies—and for communicating ideas to others.”

    • To be useful, a hypothesis should suggest what evidence would support it and what evidence would refute it. A hypothesis that cannot, in principle, be put to the test of evidence may be interesting, but it may not be scientifically useful. 1B/H9** (SFAA)
AP.3C Know that scientific theories are based on natural and physical phenomena and are capable of being tested by multiple independent researchers. Unlike hypotheses, scientific theories are well-established and highly-reliable explanations, but they may be subject to change as new areas of science are created and new technologies emerge.

Know

THAT SCIENTIFIC THEORIES ARE BASED ON NATURAL AND PHYSICAL PHENOMENA AND ARE CAPABLE OF BEING TESTED BY MULTIPLE INDEPENDENT RESEARCHERS

Including, but not limited to:

  • Components
    • Well-established and highly reliable explanations
    • Based on (natural) non-artificial phenomena, which involves the physical properties of matter and energy
    • Principles formed as an attempt to explain things that have already been substantiated by data
  • May be subject to change
    • New evidence arising that is inconsistent with or cannot be explained by current theory
    • The development of new technologies
  • Examine various scientific theories from the field of anatomy and physiology and the evidence that supports, disproves, or modifies them, such as:
    • Humoral theory of disease
      • Description: Galen relied upon the Hippocratic treatise On the Nature of Man, which stated that good health relied on the balance of four humors or bodily fluids: phlegm, blood, yellow bile, and black bile
        • Historical example – use of bloodletting in disease treatment
        • Modern modification – use of leeches and maggots in medicine to reduce inflammation and remove necrotic tissue
    • Miasmatic theory
      • Description: states the origin of epidemics was due to a miasma, emanating from rotting organic matter, and spread to susceptible people by decaying plant and animal matter, various kinds of waste, bad smells, and bad air
      • Replaced in the 1880s by the germ theory of disease
    • Germ theory of disease
      • Description: states that specific microscopic organisms are the cause of specific diseases
      • Lister – antiseptic surgical techniques
      • Koch – Koch’s postulate
      • Pasteur – pasteurization, vaccination
Note(s):
  • TxCCRS:
    • I. Nature of Science – A4 – Rely on reproducible observations of empirical evidence when constructing, analyzing, and evaluating explanations of natural events and processes.
  • Project 2061: By the end of the 12th grade, students should know that:
    • In the long run, theories are judged by the range of observations they explain, how well they explain observations, and how useful they are in making accurate predictions. 1B/H6b*
    • In science, the testing, revising, and occasional discarding of theories, new and old, never ends. This ongoing process leads to a better understanding of how things work in the world but not to absolute truth. 1A/H3bc*
AP.3D Distinguish between scientific hypotheses and scientific theories.

Distinguish

BETWEEN SCIENTIFIC HYPOTHESES AND SCIENTIFIC THEORIES

Including, but not limited to:

  • Use supporting evidence to determine whether a statement is a hypothesis or a scientific theory
Note(s):
  • Project 2061: By the end of the 12th grade, students should know that:
    • In the long run, theories are judged by the range of observations they explain, how well they explain observations, and how useful they are in making accurate predictions. 1B/H6b*
